Editing MP3 Files - MP3 Editing Software
One of the big advantages of digital audio is the ease by which it can be edited. Unwanted noises such as pops
and scratches can be automatically removed, the volume can be increased or decreased, tracks can be rearranged and
audio material can be inserted or deleted. Some of this editing falls into the domain of special effects, but a lot
of it is very useful for the average listener. For instance, wouldn't it be nice to have all of your music
collection play at the same relative level rather than having to adjust the volume for each track' And if you have
MP3 files that were converted from an analog source such as cassette or record, the sound can be improved to near
There may be some MP3 files in your music collection for which you no longer have the original source. If these

softer and soft tracks louder so that on the whole, they average out. A complete folder full of audio files can be

Normalization is such a common procedure that it is included in virtually every audio ripping program - freeware
